GW: Not against protecting bats, because they are so adept at eliminating mosquitos. I even installed a bat house near a place on my house where they were getting in. After they migrated for the season, I got some spray foam and blocked the entrance. Problem solved, although they’ve yet to use the bat house.

Jutting out into Lake Superior is the Keweenaw Peninsula, home to Michigan’s Copper Country.
This is where the earliest known metalworking in North America originated, with objects crafted by Indigenous peoples from Keweenaw copper becoming so prized that they have been discovered in archaeological sites throughout North America.
European settlers also established mining operations in the same region and made Michigan into the world’s leading copper producer by the early 20th century.
While virtually all the mining operations in the area have shuttered since then, the mines are not empty. The Keweenaw region is home to seven of Michigan’s nine bat species, with many of the bats calling the abandoned mines home.
Three of the Keweenaw’s bat species migrate south for the winter, with some, like the hoary bat, traveling as far as Central America before returning to their spring and summertime breeding grounds in North America.
The remaining four species spend their winters hibernating deep within caves and abandoned mine shafts throughout the region. Read more
